commit ed613aa66fe37737ab97ce7e483949d931a0c3a5 Author: Balazs Gibizer <balazs.gibi...@est.tech> Date: Tue Jun 4 10:36:45 2019 +0200 Change the default of notification_format to unversioned The default config `both` means that both the legacy and the versioned notifications are emitted. This was selected as default in the past when we thought that this will help the adoption of the versioned interface while we worked on to make that new interface in feature parity with the legacy. Even though the versioned notification interface is in feature parity with the legacy interface since Stein the projects consuming nova notifications do not have the resources to switch to the new interface. In the other hand having `both` as a default in an environtment where only the legacy notifications are consumed causes performance issues in the message bus hence the bug #1805659. The original plan was that we set the default to `versioned` when the interface reaches feature parity but as major consumers are not ready to switch we cannot do that. So the only option left is to set the default to `unversioned`.

As most of the openstack projects only consuming legacy notifications the emitted but not consumed versioned notifications are unnecessary loading the message bus.
